We have consolidated the tape of ALL US stock exchanges and dark pools (this means we get the TRADE IDENTIFIER showing whether the trade was a buy, sell or sell short). The data below shows just the short sales each day in your stock. It includes both EXEMPT (market makers) and NON-EXEMPT (everyone else) short sales in MAST THERAPEUTICS INC.. An average of 42.92% of the daily trading in MSTX is short selling. This is abnormally high and implies there is illicit trading taking place in your stock.

We then issue FINRA COMPLIANT research to our large user base to counteract this activity that is driving MSTX lower unfairly.
